I'm finally getting around to doing a complete tune-up on Karla's 1955 LoBoy. I'm installing a new 6v coil and a pertronix electronic unit in the distributor. This machine has a distributor and not a magneto. When disconnecting the coil I noticed the wire going to the distributor was connected to the + terminal on the coil. Before I install the new coil, is this the correct location or should it be on the - terminal? This tractor is still 6v positive ground and hasn't been altered.

Thank you.
 
My personal experience with pertoronix and 6 volts systesm has not been very good. I have used them on 12v systems, and they are great. I would stick with the points for 6 volters and use NAPA parts
napa points ECH CS1600
napa Condenser ECH IH200
napa Rotor ECH IH300
napa Cap ECH IH350
napa VR 6 v VR851
napa coil 6 ECH IC7

Thanks for the caution. Already installed the parts but I did get what I could from Napa per an earlier list you had posted. I'm going to give the pertronix a try and if it fails I will go back to points. As you started, the 12v pertronix works wonderful on my 140. That and a hot coil...it barks now.
 
Is your tractor pos or neg grounded at the battery? I've always followed the installation of the wire from the coil to the dist as: if battery pos ground, coil pos to dist. and if battery neg ground then coil neg to the dist (thus grounding the circuit when the points close, same as the battery ground). I remember reading on this forum that the coil will work either way but might last longer if it follows what I posted. JMHO Stan

Positive ground on the battery. I've got it all hooked up and have great spark now. Still seems to be hanging the float and spilling gas on the floor when I try to start it (battery needed a bit of charge though.) I'm going to drop the float bowl and see if the needle is stuck and not closing all the way. Might just pull the carb and go through it with a new kit. That's usually what I wind up doing every time.
 
Here’s what you may experience with the 6v Pertronix: you crank it to start but it does not start, until you release the pull rod, it then fires off and runs fine. The starter pulls the voltage too low to start while cranking. Maybe they have improved them by now but for that reason I’ve not recommended them. Like you, I love my 12v units, my 2 Cubs and my Cockshutt 20 start instantly with them. I avoid the high output coils, however, they put a serious strain on the electronic pick-up of the Pertronix.
